But it sure looks that way. It looks like a new wild accusations that you immediately endorse. You leave no hints at all that this isn't what you're doing.

It's very easy to avoid: "Yes, I've come to the same conclusion" indicates that the idea is not new to you (past tense) and that you believe you approached it thoughtfully. You could have said that.

"Among other reasons," instead of what you actually said (i.e. "That is clearly an irrefutable certainty just based on...") compactly suggests the existence of the plethora of reasons that you now claim you have, rather than wild overconfidence based on extremely weak evidence.

I agree I could have quoted more clearly, but I find that most everyone usually understands the context of the comment thread, so to save myself and the reader time, I typically do not. But I'm happy to try to reference better; I often do when it seems clarity will suffer otherwise and clearly my clarity was inadequate here.

The degree of antagonism is within appropriate bounds for someone who is misleading others to avoid being called out for a superficially rather heartless position.
